Abstract：Testmethodforlighttransmitanceofcarbonfiberfabricwasestablished.Lighttransmitanceofthreeplain fabricsandtwosatinfabrics were tested，andthereasons forthediferenceoflighttransmitance wereanalyzed.Theresults showedthatamong thefive kindsof domesticcarbonfiberfabrics，theorderof lighttransmitanceofcarbon fiberfabricis CF8611 > ZT7H3198P > CF3011 > CF3031 > CF8652.Light transmittance of threeplain fabricsishigher than thatof the othertwosatinfabrics.Light transmitanceofplainfabricsishigherbecauseoftheweavingproces.Thedistancebetween theinterweaving pointsof plain fabricisveryshort，andthebending ofcarbon fiberinthetowislarge，resulting inlarge weavinggap.Withtheincreaseofarealweightofcarbonfiberfabric，thecompactnessoffabricincreases，andlighttransmittance decreases accordingly.Meanwhile，the modulusandsizeofcarbonfiberarealsothereasons forthedifferenceof light transmitance.Insummary，thestablishedtestmethodforlighttransmitanceofcarbonfiberfabricisquantitativeandffective.
