Abstract

A composite carbon fiber laminate, including a first carbon fiber woven fabric layer, including one or more first voids defined between fabric strands of the first carbon fiber woven fabric layer; a second carbon fiber woven fabric layer, including one or more second voids defined between fabric strands of the second carbon fiber woven fabric layer; a core fabric layer; a first reflective layer positioned between the first carbon fiber woven fabric layer and the core fabric layer; and a second reflective fabric layer positioned between the second carbon fiber woven fabric layer and the core fabric layer, wherein the first reflective layer reflects light that is incident upon the first carbon fiber woven fabric layer at the one or more first voids.

Claims (13)

1 . A composite carbon fiber laminate, comprising:

a first carbon fiber woven fabric layer, including one or more first voids defined between fabric strands of the first carbon fiber woven fabric layer;

a second carbon fiber woven fabric layer, including one or more second voids defined between fabric strands of the second carbon fiber woven fabric layer;

a core woven fabric layer;

a first dyed reflective layer positioned between the first carbon fiber woven fabric layer and the core woven fabric layer;

a second dyed reflective fabric layer positioned between the second carbon fiber woven fabric layer and the core woven fabric layer, and

a first additional fabric layer positioned between the first carbon fiber woven fabric layer and the first dyed reflective layer, the first additional fabric layer having a first fabric area weight (FAW),

wherein the first dyed reflective layer reflects light that is incident upon the first carbon fiber woven fabric layer at the one or more first voids to maintain a color performance target of the first carbon fiber woven fabric layer,

wherein the second dyed reflective layer reflects light that is incident upon the second carbon fiber woven fabric layer at the one or more second voids to maintain a color performance target of the first carbon fiber woven fabric layer,

wherein the first dyed reflective layer has a second FAW, wherein the second FAW and the first FAW are both less than 75 grams per square meter (GSM).

2 . The composite carbon fiber laminate of claim 1 , wherein the first and the second reflective layers are dyed glass fiber fabric.

3 . The composite carbon fiber laminate of claim 1 , wherein the first and the second reflective layers are dyed carbon fiber fabric.

4 . The composite carbon fiber laminate of claim 1 , further comprising a second additional fabric layer positioned between the second carbon fiber woven fabric layer and the second dyed reflective layer, the second additional fabric layer having the first FAW.
